HoRsEsHoE-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 513,456, dated January23, 1894.

Application liled July Z0, 1893.

To all whom i# may concern.-

Be it known that I, HENRY E. DARBY, a citizen of the United States,residing at Troy, county of Rensselaer, and State of New York, haveinvented certain new and useful Improvements in Horseshoe-SwagingMachines, of which the following is a specification.

My invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the letters ofreference marked thereon,which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a view in side elevation of my improvedhorseshoe-swaging machine, broken away at its middle part to show thepresser-rolls in cross-section. Fig. 2 is a top plan view of the same.Fig. 3 is au edge view of one of the die-supporting links of the endlesscarrier, detached. Fig. 4 is a top plan view of one of theshoe-supporting swaging-dies detached. Fig. 5 is a side elcvation of thesame.

My improved machine is adapted for swaging horseshoes after the samehave been formed by bending horseshoe-blanks in any p 3o known manner.

The object of my invention is to provide an endless carrier for theswaging-dies which will cause the dies to properly present the formedshoes to the presser-rolls to be swaged there` by, and afterward causethe swaged shoes to be discharged by gravity from the swagingdies. Whenthe' swaging-dies are presented to the presser-rolls by an endlesscarrier movable in a horizontal plane upon drums rotary on verticalaxes, with the dies secured on one side only to the carrier, asheretofore prac# Serial No. 480,986. (No model.)

sides of the respective dies, whereby the dies are properly presented tothe rolls and maintained in a proper position during the swagingoperation, and afterward inverted to discharge the swaged shoe from thedies by gravity.

A is the bed of the machine, the upper surface of which forms a table Aon which the shoe-supporting swaging-dies B rest as they are carried toand from 'the horizontal presser-rolls O, O', each of which rolls hasend -beariugs in the uprights A2 erected from opposite sides of the bed.The presserrolls are located the proper distance apart for the upperroll to bear upon a die-supported shoe when the bottom of the die restsupon the lower roll, in passing between the rolls, and properly swagethe shoe, or make it conform to the shape `of the die-surface. Thesupporting and swaging surfaces of the dies may be of any known form.The dies are supported and presented successively to the presser-rollsby means of an endless carrier comprising the chains, D, D', supportedupon and driven by drums in the form of sprocket-wheels, D2, D3 mountedupon shafts D4, D5 which have bearings in the bed A at opposite ends ofthe machine.

The drums are rotary on horizontal axes, parallel with each other andparallel with the axes of the presser-rolls, whereby the carrier is madeto travel in a vertical plane bisecting the presser-rolls at rightangles to their axial lines, and so located relatively to the rolls thatthe carrier passes between the rolls, and from upper to lower side ofthe drums.

The swaging-dies are severally provided with the usual die-center Bshaped to fit the interior of the shoe and raised from the planeanvil-surface B2, on which the shoe rests when presented to thepresser-rolls. The raised portions, B3 are adapted to give to the outersurfaces of the heel of the shoe, or to maintain therein, a correct formduring the swaging operation.

The swaging-dies are severally provided on their opposite sides with arecess B4 adapted to receive a supporting pivot DG projecting`interiorly one from each of a pair of oppo- IOO ended slots B4, in theopposite sides of the die-block, and each is provided on its inner endwith a cylindrical head D9 adapted to enter the chambered recess B7 inthe dieblock. I am thus able to pivotally support the dies on oppositesides which causes both sides of the die to continuously travel at thesame rate of speed and properly present the shoes to the rolls andmaintain them in proper position during the swaging operation. The dies,thus connected with the carrier, can be easily detached or replaced incase of breakage or wear.

It is only necessary to run the carrier around until the die to beremoved is opposite the openin g F in the bed or frame, at which pointthe die can be easily raised from the carrier and withdrawn through theopening and another die substituted in its place in the carrier. Whenthe carrier-supported dies are face upward, their backs rest upon theplane upper surface of the bed along which they slide, and by which theyare confined within the carrier.

As the dies are sucessively carried from between the rolls on the upperside of the bed they are each inverted, as the carrier passes fromtheupper to the lower side of the drum, and the swaged shoe falls from thedie by gravity into a suitable receptacle not shown.

The carrier-chains run parallel with each other and may be a pair ofseparate detached chains, or connected at intervals, as indicated bydotted lines G in Fig. 2, thus forming practically a single chain, theessential feature of my invention being a supporting connection betweenthe carrier and two opposite sides of the die.

By pivotally connecting the die on opposite sides with the carrier, sothat the axial line of such connection is parallel with the axes of thepresser-rolls, as shown, the die is free to oscillate on such axial linein passing between the presser-rolls, whereby the strain upon the dieand carrier is lessened.

Power is applied to the upper presser-roll through the pulley C2 fixedupon the roll-trunnion C3, and may be transmitted to the carriersupporting drums by means of the pulley 04 also fixed upon the trunnionC3, the pulley C5 fixed upon the sprocket-wheel shaft D4 and theconnecting belt C6.

What I claim as new, and desire to secure by Letters Patent, is-

1. In ahorseshoe-swaging machine, the combination with a pair ofpresser-rolls,and drums severally rotary on parallel axes, of a pair ofparallel carrier-chains supported and driven by the drums, andshoe-supporting dies supported by and between the carrier-chains,substantially as described.

2. In a horseshoe-swaging machine, the combination with a pair ofpresser-rolls, and an endless carrier, of a shoe-supporting diepivotally connected on opposite sides with the carrier, substantially asdescribed.

3. In a horseshoe-swaging machine, the combination with a pair ofpresser-rolls, and an endless carrier, of a shoe-supporting die, and adetachable hook-and-eye connection between the die and carrier,substantially as described.

4. In a horseshce-swaging machine, the combination with a pair ofpresser-rolls, of an endless carrier, and a shoe-supporting diepivotally connected with the carrier on an axial line parallel with theaxes of the presser-rolls substantially as described.

In testimony whereof I have hereunto set my hand this 11th day of July,1893.
